    摘要: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method, for a user equipment (UE) is disclosed. The method comprises: transmitting, by the UE to a network entity, a registration request message including a registration type information element (IE) indicating a periodic registration updating or a mobility registration updating; receiving, by the UE from the network entity, a registration accept message including a pending network slice selection assistant information (NSSAI); and determining, by the UE, that a previously received allowed NSSAI as invalid based on the registration accept message.

    摘要: A method and system in the User Equipment (UE) for maintaining rejected network slice selection assistance information (NSSAI) for Single Network Slice Selection Assistance Information (S-NSSAI) not available due to maximum number of UEs reached per access type. The method comprises receiving a Non-Access Stratum (NAS) message including at least one of a registration accept, registration reject or CONFIGURATION UPDATE COMMAND message along with at least one of rejected Single Network Slice Selection Assistance Information (S-NSSAI(s)) information and a cause for the S-NSSAI not available due to maximum number of UEs reached from a network. Thereafter, the method includes determining by the UE an access type on which the rejected S-NSSAI(s) is applicable based on the received S-NSSAI(s) information and then maintaining a storage of the rejected NSSAI for the S-NSSAI not available due to the maximum number of the UEs reached per access type based on the determination.

    摘要: The present disclosure may be related to a pre-5G or 5G communication system to be provided for supporting higher data rates Beyond 4G communication system such as LTE. A method, for a UE in a network comprising the UE and an AMF entity, is disclosed. The method comprises: identifying that the UE in idle mode, has an emergency protocol data unit (PDU) session, transmitting, to the AMF, a control plane service request (CPSR) message comprising data of a first type, receiving, from the AMF, a security mode command message indicating that an integrity check related to the CPSR message has failed, in response to receiving the security mode command message, identifying whether the CPSR message comprises the data of the first type including data of a second type, or the CPSR message comprises the data of the first type excluding the data of the second type, and transmitting the CPSR message excluding the data of the first type except the data of the second type.
